.net 3.2?
...
Interesting.
Also, .net 3.5 should run on any up to date XP installation.  Really, upgrading to .net 3.5 is not unreasonable.  There is a lot of fantastic functionality added in it, specifically functionality that make applications like R2P much easier to write and maintain.  Also, .Net 4 is right around the corner (with more really cool functionality added.)
If you're using some hacked version of XP where you cannot update, then I doubt many will feel much sympathy.
